Hohenzollern-Sigmaringen

Hohenzollern-Sigmaringen is the cadet branch of the senior Swabian branch of the Hohenzollern dynasty, less known however than the Franconian branch which became Burgraves of Nuremberg and later ruled Brandenburg, Prussia and ultimately Germany in the centuries to 1918. The Princes of Hohenzollern-Sigmaringen ruled over a small principality in southwest Germany. Unlike the Hohenzollerns of Brandenburg, the Hohenzollern-Sigmaringens and their cousins of Hohenzollern-Hechingen, the seniormost branch of the House of Hohenzollern, remained Catholic.
